Player disconnected

After some time, I’m disconnected from the server, what could be the problem and how to solve it?

Plugins: ViaVersion, ViaBackwards, ViaRewind, Chunky.
Paper version: #204 (1.16.3)

Gonna have to post some logs of some kind. Preferably the server ones when you are disconnected.

i am having a similar problem, my mc version is 1.16.4, paper-1.16.4-393.jar, plugins: AFK, BetterSleeping, ChangeSkin, FastAsyncWorldEdit, HealthBar, ImageOnMap, LoginSecurity, MinableSpawners, ProtocolLib and SkinsRestorer
the disconnect message: [22:04:08 INFO]: mihabozic321 lost connection: Disconnected
it just says “Disconnected” on the client
is this a normal thing that can be prevented in the config?
we have afk farms and its annoying if it disconnects us randomly
thanks
